Though CFS2 is an older sim, it cannot be equaled in flexibility, and simmers who have left keep coming back.  And a great place to re-enter the senior sim is with the Fox Four Korean campaigns.  The Fox Four site features four self-contained and self-installing campaigns, and lots of updates on the Extras page...not to mention the fine ships on the CG's Shipyard page.

Though it contains some duplication from the Extras page, some additonal extras are to be found on Tango_Romeo's page:
